'- Said revolving plug 29 is provided with a gins slightly beyond or near the axial center go of said revolving plug 29, and the other edge reaches to the periphery of said plug.- Said crescent shaped plates 30 adjacent their centers and at the inner peripheries thereof have V notches 33 which are adapted to register with 2:; slot 32in order that key 34 may be inserted.

' Interposedbetween the inner end of the revolving plug 29 and-head 24 and set by its wing portion and tooth 35 within cylinder 27 is plate 36 havingcentralopening 37. Said to. plate 36 centrally of its wing portion 34 and in alinement with tooth 35 has notch or slit' 38 which isin alinement with notches 33 of the crescent-shaped plates 30, and which registers with'slot 32 when revolving plug 29 is 35 set in proper position for insertion of key 34.v Itis to be observed that the-inner periphery of plate 36 remains at a plane'which is nearer tothev center of cylinder 27 than the inner peripheries of the crescent shaped plates 30 for. the purpose which will be presently mentioned. V i w Key34 at oneof its edges is provided with two recesses 39 registering with the crescent shaped plates 30. Adjacent one of itsends said key 34 is provided with another recess 40 registering with washer plate 36 when the key is in operative position within slot 32 of the revolving plug 29. Byvirtue of the fact that the innerperiphery of the washer plate 7 36 is nearer to the center of cylinder 27 than are the inner. peripheries of the crescentshaped plates 30, recess 40 is necessarily deeper than recesses 39. Thus, by varying the width of said crescent-shaped plates 30 and 05 42, as clearly seen on .Fig. 4.-- Extending plug 29. The inner peripheral portions of...

with notches 33 and 38 of the crescent-shaped plates 30 and washer plate 36, respectively, for receiving therewithin' the end of key 34 for the purpose hereinafter described.

At t-helowermost point at the periphery of barrel 41 and adjacent plate 26, a housing 44-,ii1cluding bottom wall 45, is provided, the walls of said housing44 being in any suitable manner af'ixed either to said barrel 41 orto 8 said plate 26 or to both. Receivable within said housing 44 is a plunger'pin 46, adapted to longitudinal slot 32, one edge of which beenter into an opening made in cylinder 28 and adapted to enter and extend into slot 43 of head 24. The opposite end of said plunger pln 46'is provided with head 47 adapted to sh ft within'said housing 44 and within the registering opening made in the body of barrel 41.: interposed between said head 47 and bottom wall 45 of said housing 44 is a coil spring 99 48 urging said plunger pin 46 towards and into slot43. 7 f 7 t When key 34 remains out of position within slot 32 and slot 43', as shown in Fig. 4, the plunger pin 46 remains within said slot 43 and thus prevents any rotary movement of head 24 and shaft 23'. Theend of'the key, which may be slightly tapered at the point of the first engagement thereof with the end of the plunger pin 46, as the same enters into said slot 43, is adapted to displace said plunger pin 46 from said head 43 and drive the same inwardly of housing 44 against the tension of spring 48. As soon as this is accomplished, key 34, by virtue of its engagement with head 24, will'be adapted to rotate shaft 23. The rotary movement thus imparted to shaft 23 and itsgear 22 willbe transmitted to gears 21 and 19 upon shaft 20. The rotating gear 19 upon said shaft 20 will shift bolt 17 into locked or unlocked position with respect to the keeper plate 49 and its head 50 which is provided with opening 51- for receiving the adjacent end or bolt 17.. 0f course, the movement of-bolt 17 into one or the'other direction depends upon the direction of turning of key, 34, head 24 and shaft23. I V e j V e Said plate 49 is affixed by a plurality of screws '52 to wall 53. To conceal said plate 49 door-frame 54 may be placed upon said plate49. A

As is apparent from the hereinabove description, plate 26 is not in any way permanently attached to casing 10 or its plate 14. As was said, said plate 26 is receivable within space defined by rmolding 15. Likewise head 24 of shaft 23 is adapted to freely'enter cylinder 27 at its "inner end. As said head 24 is inserted within said cylinder 27, plunger pin 46 freely enters slot 43.

To place the look upon door 55 opening 56 is made therein for positioning therewithin barrel 41. Likewise suitable space is scoo ed out from the body of the doorto accommo ate housing 44. When saidhousing 44 and barrel 41 are in position within opening 56 of door 55, and plate 26 contacts with the adjacent face of the door, screws 57 are passed through said plate 26 and driven into door 55. Thereupon casing 10, including plate 14, is positioned upon said plate 26, and preparatory thereto head 24 is shifted within cylinder 27. Thereupon screws 58 are passed through registering openings made in flanges 12 and 13, plate 14 and its molding 15, and thereupon said screws 58 are driven into the door 55. Thus, by this means plate 26 will be held in position with respect to plate 14 and its molding 15, as well as head 24 within cylinder 27. t

It is to be observed that as long as suitable and proper key is not inserted within slots 32 and 43, it will not be possible to rotate head 24 and shaft 23 for shifting bolt 17 in either direction, because plunger pin 46 remaining within slot 43 prevents rotary move ment of head 24. As soon as said plunger pin 46 is displaced from within said slot43 and driven into housing 44 by a proper key, as hereinabove described, head 24 may be rotated, and the adjacent free end of said plunger pin 46 will ride upon the periphery of head 24, which pin will not spring back into slot 43 until said slot 43 comes in aline ment with said plunger pin 46 when brought to that position by key 34, and as soon as said key is withdrawn plunger pin 46 will spring into slot 43.

It is further observed that the ends of casing 10 proper are constricted, the bottom and upper walls thereof contacting with bolt 17 thus keeping the same in position and preventing its lateral shifting movement.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

V] hat I claim as new is:

1. A lock comprising a casing, a bolt slidable therein, a cylinder supported by and projecting rearwardly from one wall of the casing, bolt operating means including a shaft jo-urnaled within the casing and having a relatively large cylindrical portion received by said cylinder, a plug rotatably mounted in said cylinder in end to end relation with said cylindrical portion of the shaft, said plug and cylindrical portion of the shaft having aligned key receiving slots, a housing surrounding said cylinder and ineluding an offset portion, said cylinder and cylindrical portion of the shaft having aligned openings, and a spring influenced key and cylindrical portion of the shaft having aligned key receiving slots, said plug having spaced annular grooves, crescent shaped plates fitted in said grooves and having notches aligned with said keyreceiving slots,

a housing surrounding said cylinder and having an offset portion, said cylinder and cylindrical portion of the shaft having aligned openings, .and a spring influenced key retractablepin supported within the ofl' set portion of the housing and normally positioned in said openings to hold the shaft against rotation.

In testimony whereof JOHN WEBER.

I atfix my signature."
